NFL Roundup: Knee injury ends Manuel's preseason

Buffalo Bills rookie quarterback EJ Manuel will have a minor knee operation and miss at least the rest of the preseason, the team announced Saturday.

Manuel had swelling in his left knee a day after his strong performance in Friday's preseason win over the Minnesota Vikings. He completed 10 of 12 passes for 92 yards with a touchdown.

First-year coach Doug Marrone said in a statement released by the team that Manuel will be re-evaluated at the end of the preseason. Kevin Kolb will start the Bills' next preseason game against the host Washington Redskins on Aug. 24.

Also, wide receiver Kevin Elliott will miss the rest of the season with a torn ACL.

---The San Diego Chargers announced Saturday that wide receiver Eddie Royal, who left practice Saturday in an ambulance, has a bruised lung and a concussion.

Royal fell hard to the ground while trying to make a catch during a drill. He was able to get up and walk to the trainer's area before going back down. He was treated with an oxygen tank. Royal was then carted off and taken away in an ambulance that arrived on the scene. Coach Mike McCoy said that Royal was having trouble breathing before he was transported to the hospital.

Royal is in his second year with the Chargers. He had 23 catches for 234 yards with a touchdown last year. He spent the first four years of his career with the Denver Broncos.
